Image acquisition visuals for augmented reality

ABSTRACT

Various embodiments of the present disclosure encompass a visual image sequence controller ( 40 ) for controlling an augmentation of a visual imaging sequence acquisition of an interventional imaging sequence in a rendered augmented view of an image-guided intervention by an augmented reality device ( 30 ). The visual imaging sequence acquisition ( 42 ) includes, for each inter-ventional image of the interventional imaging sequence ( 23 ), an interactive virtual indicator of a sequence number of a corresponding interventional image within the interventional imaging sequence ( 23 ) and an imaging parameter of the imaging modality ( 20 ) (e.g., a direction, a rotation and/or an angulation of the imaging modality ( 20 )) during an acquisition of the corresponding interventional image by the imaging modality ( 20 ). The controller ( 40 ) interfaces with the imaging modality ( 20 ) and/or a display ( 24, 31 ) responsive to a user interaction with at least one of the interactive virtual indicators.

FIELD OF THE INVENTION

The present disclosure generally relates to image-guided interventions for a diagnosis and/or a treatment of a three-dimensional (3D) anatomy. The present disclosure specifically relates to an incorporation of augmented reality into image-guided interventions.

BACKGROUND OF THE INVENTION

Two-dimensional (2D) interventional images (e.g., X-ray images, ultrasound images, etc.) are inherently projections of complex three-dimensional (3D) anatomy. To get a sense of a structure of the 3D anatomy during an imaging guided-diagnosis, multiple projections of the 3D anatomy taken from multiple angles of a 2D imaging modality relative to the anatomy are needed. For this reason, in an image-guided intervention, a clinician is provided an opportunity to control a positioning and/or an orientation of the 2D imaging modality to thereby acquire 2D interventional images from a variety of angles (e.g., a clinician manual or programmed control of a C-arm of an X-ray system, a clinician manual or programmed control of a robotic ultrasound probe, etc.).

After a diagnosis of a diseased 3D anatomy via the 2D/3D interventional images, the clinician may decide to treat the diseased 3D anatomy by using interventional tools at the disposal of the clinician. For such an image-guided surgery, the imaging modality is designed to be able to find the optimal viewing angle for visualizing the diseased area as well as positioning and/or an orientating of interventional tools within the diseased area.

In all, during a typical image-guided intervention for diagnosis and/or a treatment of 3D anatomy, a large number of images are taken from a large number of different angles.

More particularly, the clinician frequently needs to access the 2D interventional images taken from previous positions (or even a previous procedure) to validate the diagnosis of the 3D anatomy, to check for anomalies within the 3D anatomy and/or to validate the accuracy of the treatment of the 3D anatomy. Although an imaging modality stores geometry information with the 2D interventional images (e.g., an angulation/rotation of a C-arm, a mechanical scanning of an ultrasound probe, etc.), such geometry information is only available as a linear list. Thus, the clinician needs to make a mental picture of the image-guided intervention to know where an image sequence was taken at which time(s) and at which location(s). Especially for novice users and very long procedures, it is sometimes difficult to get an overview of the whole procedure. So, a clinician typically must navigate through an image sequence linearly, one by one, until they find the 2D interventional image(s) for validating the diagnosis of the 3D anatomy, checking for anomalies within the 3D anatomy and/or validating the accuracy of the treatment of the 3D anatomy.

SUMMARY OF THE INVENTION

It is an object of the present disclosure to provide novel, unique 2D/3D interactive virtual indicators in an augmented reality of an image-guided intervention (e.g., X-ray interventional imaging for diagnosis and/or treatment of 3D anatomy, ultrasound interventional imaging for diagnosis and/or treatment of 3D anatomy, etc.) for graphically displaying, within a physical world, geometric information of an imaging modality associated with a sequential acquisition of 2D/3D interventional images. This advantageously enable interaction of a user, such as a clinician, with a sequence of a portion or an entirety of the image-guided intervention in a natural, yet intuitive way, thereby improving workflows, decision speed and diagnosis and/or treatment quality by enabling the clinician to ascertain an overview of a diagnostic phase and/or a treatment phase of the image-guided intervention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present disclosure is applicable to image-guided intervention implementing minimally-invasive imaging to diagnose and/or treat anatomical diseases (e.g., X-ray interventional imaging of organs, ultrasound interventional imaging of organs, etc.).

The present disclosure improves upon the prior art of image-guided intervention by providing unique embodiments of 2D/3D interactive virtual indicators in an augmented reality of an image-guided intervention (live or recorded) for graphically displaying, within a physical world, geometric information of an imaging modality associated with a sequential acquisition of 2D/3D interventional images to thereby illustrate a sequence of a portion or an entirety of the image-guided intervention to a clinician in a natural way.

To facilitate an understanding of the present disclosure, the following description of FIGS. 1 and 2 teaches respective exemplary embodiments of an augmented image-guided intervention system and an augmented image-guided intervention method in accordance with the present disclosure. From the description of FIGS. 1 and 2 , those having ordinary skill in the art of the present disclosure will appreciate how to apply the present disclosure to make and use additional embodiments of augmented image-guided intervention system of the present disclosure and augmented image-guided intervention method of the present disclosure.

Referring to FIG. 1 , an exemplary augmented image-guided intervention system of the present disclosure employs an imaging modality 20, an augmented reality device 30 and a visual image sequence controller 40.

For purposes of describing and claiming the present disclosure, the term “imaging modality” encompasses all systems, as known in the art of the present disclosure and hereinafter conceived, for implementing an image-guided intervention procedure by directing energy (e.g., X-ray beams, ultrasound, radio waves, magnetic fields, light, electrons, lasers, and radionuclides) into an anatomy for purposes of generating images of the anatomy (e.g., biological tissues and bone). Examples of an imaging modality include, but are not limited to, interventional X-ray imaging systems and interventional ultrasound systems.

In practice, imaging modality 20 includes an interventional imaging controller 22 for controlling an activation/deactivation of an interventional imaging device 21 (e.g., an X-ray C-arm, an ultrasound probe, etc.) to systematically direct energy into an anatomy via operator-generated commands and/or image guided procedural-generated commands for purposes of generating images of the anatomy as known in the art of the present disclosure.

For purposes of describing and claiming the present disclosure, the term “augmented reality device” encompasses all devices, as known in the art of the present disclosure and hereinafter conceived, for implementing an interactive experience of overlaying virtual object(s) in a physical world of image-guided intervention based on an accurate spatial registration of the augmented reality device to the physical world of image-guided intervention that facilitates a consistent positioning and orienting of the virtual object(s) in the real-world image-guided intervention. Examples of an augmented reality device include, but are not limited to, Microsoft Hololens®, Microsoft HoloLens®v2, DAQRI Smart Glasses ®, Magic Leap®, Vusix Blade® and Meta2®.

In practice, augmented reality device 30 includes an augmented reality controller 32 for controlling augmented reality display 31 to display virtual object(s) in a physical world of image-guided intervention based on an accurate spatial registration of augmented reality display 31 to imaging modality 20 and/or the subject anatomy that facilitates a consistent positioning and orienting of the virtual object(s) to the subject anatomy and an operater-interaction with the virtual object(s).

For purposes of describing and claiming the present disclosure, the term “visual image sequence controller” encompasses all structural configurations, as understood in the art of the present disclosure and as exemplary described in the present disclosure, of a main circuit board or an integrated circuit for controlling an application of various principles of the present disclosure for an augmentation of a visual imaging sequence acquisition of an interventional imaging sequence in a rendered augmented view of the image-guided intervention by an augmented reality device as exemplary described in the present disclosure. The structural configuration of the controller may include, but is not limited to, processor(s), computer-usable/computer readable storage medium(s), an operating system, application module(s), peripheral device controller(s), slot(s) and port(s).

For purposes of describing and claiming the present disclosure, the term “application module” broadly encompasses an application incorporated within or accessible by a controller consisting of an electronic circuit (e.g., electronic components and/or hardware) and/or an executable program (e.g., executable software stored on non-transitory computer readable medium(s) and/or firmware) for executing a specific application associated with implementing an augmentation of a visual imaging sequence acquisition of an interventional imaging sequence in a rendered augmented view of the image-guided intervention by the augmented reality device

In practice, as exemplary described in the present disclosure, visual image sequence controller 40 access an intervention file 41 informative of geometric information of imaging modality 20 associated with an acquisition of 2D/3D interventional images to thereby control an augmentation of a visual imaging sequence acquisition of an interventional imaging sequence by imaging modality 20 in a rendered augmented view of the image-guided intervention by augmented reality device 30. The visual imaging sequence acquisition includes, for each interventional image of the interventional imaging sequence, an interactive virtual indicator of a sequence number and an imaging direction during an acquisition of the interventional image by imaging modality 20.

More particularly, augmented reality controller 32 facilitates a rendering of computer generated content as overlay on an augmented view of an image-guided intervention. When a pose of the eyes are known by augmented reality controller 32, the visual imaging acquisition 42 can be rendered such that it appears to be part of the image-guided intervention. For this to happen, augmented reality device 30 and the subject anatomy need to be accurately tracked. This may be accomplished via a camera (e.g., visual or ToF) of augmented reality device 30 as known in the art of the present disclosure and/or a surgical navigation system as known in the art of the present disclosure. Additional detection of augmented reality device 30 and the subject anatomy adds may be appropriate for additional accuracy, such as, for example, fiducial marker(s), active marker(s), etc.

Further in practice, visual image sequence controller 40 may interface with a display (not shown), as known in the art of the present disclosure or hereinafter conceived, for displaying an interventional image as commanded by an user-activation of an interactive visual indicator of the present disclosure. Visual image sequence controller 40 may interface with interventional imaging controller 22, as known in the art of the present disclosure or hereinafter conceived, for controlling a re-posing of interventional imaging device 21 as commanded by user-activation of an interactive visual indicator of the present disclosure.

An augmented reality image-guided intervention method of the present disclosure involves, subsequent to or during an acquisition of an interventional imaging sequence by imaging modality 20, augmented reality controller 32 controlling an augmentation of an augmented view of the image-guided intervention via an augment reality display 32 of a visual image sequencing acquisition 42 generated by visual image sequencing controller 40 to include interactive virtual indicators of sequence numbers and imaging directions of the interventional imaging sequence.

For example, FIG. 2 illustrates an exemplary execution of an augmented image-guided intervention method of the present disclosure by the augmented reality image-guided intervention system of FIG. 1 .

Referring to FIG. 2 , during an image-guided intervention, imaging modality 20 is shown in the form of an X-ray imaging system having a C-arm 21 a for acquiring an interventional imaging sequence 23 at different poses of C-arm 21 a. For this image-guided intervention example, the X-ray imaging system has acquired of four (4) sequential X-ray images, each at a different pose of C-arm 21 a and interventional imaging controller 22 generates a database listing of each X-ray image with corresponding C-arm pose information and an optional annotation by a clinician.

Still referring to FIG. 2 , visual image sequence controller 40 accesses an interventional file 41 consisting of the database listing by interventional imaging controller 22 to generate visual imaging sequence acquisition 42 a including, for each interventional image of the interventional imaging sequence 23, an interactive virtual indicator of a sequence number and an imaging direction. Augmented reality controller 32 augments an augmented view of the image-guided intervention via an augmented reality display 31 a with the visual imaging sequence acquisition 42 a of four (4) interactive virtual indicators.

In practice, an interactive virtual indicator may have any form, shape and color to convey a corresponding sequence number and imaging direction. For this example, the interactive virtual indicators are formed as vectors of an arrow shape starting from the center of the projection on the patient and extending outward to the center of the detector position. Next to the end-point of the vector, the sequence number of the interventional image appears.

An interactive virtual indicator may be any virtual indicator with witch a user, such as a clinician, is able to interact with; allowing a (two-way) communication or flow of information between a user one or more computers or one or more processors or any device embedding or connected to such computer(s) or processor(s). A clinician may interact with an interactive virtual indicator via using gestures, voice commands or other interactive modes of augmented reality display 31 a as known in the art of the present disclosure or hereinafter conceived.

The interventional images of the interventional image sequence 23 are hidden by default, as not to clutter augmented reality display 31 a. Only a ‘selected’ interactive virtual indicator will show a pictorial image 33 corresponding to the ‘selected’ interactive virtual indicator within a display as known in the art of the present disclosure or hereinafter disclosed (e.g., a display of imaging modality 20, augmented reality display 31 or an additional display monitor).

While the interactive virtual indicators may correspond to interventional images acquired at different poses of C-arm 21 a, the image-guided intervention may involve an acquisitions of a temporal series of interventional images at the same pose of C-arm 21 a as will be further discussed in the present disclosure. For this embodiment, the interactive virtual indicator may be a vector showing the imaging direction of the C-arm 21 a with an associated stack of sequence numbers.

To facilitate an understanding of the present disclosure, the following description of FIGS. 3-16 provides exemplary image-guided intervention in accordance with the present disclosure. From the description of FIGS. 3-16 , those having ordinary skill in the art of the present disclosure will appreciate how to apply the present disclosure to any type of image-guided intervention.

The first exemplary image-guided intervention involves a diagnosis X-ray imaging phase as shown in FIGS. 3-6 and a treatment X-ray imaging phase as shown in FIGS. 7-9 .

More particularly, FIGS. 3A-3C illustrates an acquisition of an interventional imaging sequence of diagnostic X-ray images 23 a-23 c at different poses of C-arm 21 a. FIG. 4 illustrates an augmented view of the diagnostic phase of the image-guided intervention via an augmented reality display 31 a including three (3) interactive virtual indicators of a sequence number and image direction of diagnostic X-ray images 23 a-23 c, respectively. An image 33 a corresponding to a selected interactive virtual indicator along with any annotation 43 a may also be displayed in augmented reality display 31 a and/or the diagnostic X-ray image 23 a-23 c corresponding to selected interactive virtual indicator may be displayed via a display 24 b.

Additionally, if a clinician wishes to return C-arm to a previous pose for purpose of reacquiring a better interventional image at that pose, the clinician may tap the correct interactive virtual indicator or a virtual object C-arm (not shown) and an interventional imaging controller will move the C-arm to the recalled pose. For example, while C-arm 21 a is in the pose of FIG. 3C, if the clinician has selected the interactive virtual indicator 1 associated with the C-arm pose of FIG. 3A, the clinician may tap interactive virtual indicator 1 to move the C-arm 21 a from the pose of FIG. 3C to the pose of FIG. 3A as exemplary shown in FIG. 6 .

FIGS. 7A-7C illustrate a temporal acquisition of an interventional imaging sequence of treatment X-ray images 23 d-23 f at the same pose of C-arm 21 a. FIG. 8 illustrates an augmented view of the treatment phase of the image-guided intervention via an augmented reality display 31 a including six (6) interactive virtual indicators of a sequence number and image direction of diagnostic X-ray images 23 a-23 c and treatment X-ray images 23 d-23 f, respectively. An images sequence 33 b corresponding to a selected interactive virtual indicator of the treatment X-ray images 23 d-23 f along with any associated annotation 43 b may also be displayed in augmented reality display 31 a and/or treatment X-ray images 23 d-23 f corresponding to selected interactive virtual indicator may be displayed via a display 24 b.

The second exemplary image-guided intervention involves a diagnosis ultrasound imaging phase as shown in FIGS. 10-13 and a treatment ultrasound imaging phase as shown in FIGS. 14-16 .

More particularly, FIGS. 10A-10C illustrates an acquisition of an interventional imaging sequence of diagnostic ultrasound images 23 g-23 i at different poses of robotic ultrasound probe 21 b. FIG. 11 illustrates an augmented view of the diagnostic phase of the image-guided intervention via an augmented reality display 31 a including three (3) interactive virtual indicators of a sequence number and image direction of diagnostic ultrasound images 23 g-23 i, respectively. An image 33 c corresponding to a selected interactive virtual indicator along with any annotation 43 c may also be displayed in augmented reality display 31 a and/or the diagnostic ultrasound image 23 g-23 i corresponding to selected interactive virtual indicator may be displayed via a display 24 c.

Additionally, if a clinician wishes to return robotic ultrasound probe to a previous pose for purpose of reacquiring a better interventional image at that pose, the clinician may tap the correct interactive virtual indicator or a virtual object robotic ultrasound probe (not shown) and an interventional imaging controller will move the robotic ultrasound probe to the recalled pose. For example, while robotic ultrasound probe 21 b is in the pose of FIG. 10C, if the clinician has selected the interactive virtual indicator 1 associated with the robotic ultrasound probe pose of FIG. 10A, the clinician may tap interactive virtual indicator 1 to move the robotic ultrasound probe 21 b from the pose of FIG. 10C to the pose of FIG. 10A as exemplary shown in FIG. 13 .

FIGS. 14A-14C illustrate a temporal acquisition of an interventional imaging sequence of treatment ultrasound images 23 j-23 l at the same pose of robotic ultrasound probe 21 b. FIG. 15 illustrates an augmented view of the treatment phase of the image-guided intervention via an augmented reality display 31 a including six (6) interactive virtual indicators of a sequence number and image direction of diagnostic ultrasound images 23 g-23 i and treatment ultrasound images 23 j-23 l, respectively. An images sequence 33 d corresponding to a selected interactive virtual indicator of treatment ultrasound images 23 j-23 l along with any associated annotation 43 d may also be displayed in augmented reality display 31 a and/or treatment ultrasound images 23 j-23 l corresponding to selected interactive virtual indicator may be displayed via a display 24 b.
